UNITED STATES JOHN LALLY, OF GREAT NECK, NEW YORK.

BUlLDING COLUMN.

Application filed February 23, 1924. Serial No. 694,618.

New York, have invented certain new and useful Improvements in Building Columns,

of which the following is a specification.

My invention relates to building columns and it is my object to produce a column in i which rolled stock is employed to build up the head or crown and which will have great load carrying capacity. In this way expensiye castings are obviated and cheap, strong, easily procured structural steel parts are used, making the column not only lighter and cheaper but stronger.

In the drawing Fig. 1 is a View, partly in section, of one form of my improved con struction, Fig. 2 a bottom view (on a smaller scale) of the structure of Fig. l on the line 22 thereof; Fig. 3 a side view, partly in section, of a modified form of bracket; and Fig. 4 a detail View of the bracketiof the structure ofFig. 3.

In the form shown in Figs. 1 and 2 the .metal casing 1 is slotted at 2, adjacent its end. The top, or crown plate, 3 has an aperture 4 therein near its edge. A shaped metal strut or brace 5 has a lug 6 on its up per end engaging the aperture 4 in the, crown plate making a mortise and tenon connection. The lower part of the strut 5 passes through the slot 2,in the casing and has a notch 7 engaging the lower end of the slot. The upper, inner'corner of the portion of the strut within the casing may be cut ed to facilitate entry of the strut into the slot.

To assemble the parts the notch 7 of the strut is hooked into the slot 2 in the casing wall, which slot is slightly longer than the heighth of the lower end of the strut, and a filling block 8, is driven in to fill the slot. The top plate 3 is next laid on the column with the lug 6 in'the aperture 4. The lug and aperture may be welded or riveted together and the lower part of the strut may be welded to the casing, either inside or outside or both and the filler block 8 may be in like manner welded in place. The casing may be filled with plastic material 9, such as concrete.

When the load comes onthe crown plate the strut 5, being held firmly at its upper end, transmits the thrust to the lower en where the toe of the notch 7 on the outside of the casing resists the inward thrust, while the notched end in contact with the bottom of the slot resists the downward thrust.

In the modification shown in Figs. 3 and 4 the strut or bracket is formed of a piece of T-beam 10 provided with the lug 11 on its upper end to engage the aperture in the top plate while the lug l2passes through the slot in the casing, the flange or head 1.3 of the T-section running from the casing wall to the under side of the top plate. giving greater resistance to downward and twisting loads on the top plate. The toe 14 at the lower end of the strut engages the casing below the slot and resists inward pressure as in the structure of Fig. 1.

The T-section strut may be welded to the casing and the lug 11 may be welded or riveted to the top plate. The strut 10 may completely fill the angle between the casing wall and top plate, when it becomes in client a bracket, or may be in skeleton form as in Fig. 1.

1. A building column comprising a casing slotted near its end, an apertured crown.

vplate on the end thereof, a strut running from the crown plate to the casing, a lug 0n the upper end of the strut engaging the aperture in the crown plate, the lower end of said strut entering the casing slot, and a toe on the lower end of the strut hearing against the outer face of the casing below the slot.

2. A building column comprising a casiug slotted near its end, an apertured crown plate on the end thereof, a strut running from the crown plate to the casing, 9. lug on the upper end of the strut engaging the aperture in the crown plate, the lower end of said strut entering the casing slot, and a toe on the lower end of the strut hearing against the outer face of the casing below the slot, the slot walls and strut faces being welded together and the lug and aper-' ture being permanently united.

3. A building column comprising a casing slotted near its end, an apert-ured crown plate on the end of the casing, a strut, a lug on its outer end engaging the aperture in the crown plate, the lower end of said strut entering the casing slot and extending below the bottom-of the slot.

4. A building column comprising a casd ing slotted near its end, an apertured crown plate on the end of the casing, a strut, a lug on its upper end engaging the aperture in the crown plate, the lower end of said strut entering the casing slot and extending below the bottom of the slot and a filling block closing the upper end of the slot.

5. A building column comprising'a cas ing slotted adjacent its end, an apertured crown'plate on the end of the casing, a strut of T-section, a lug on 'its outer end engaging the aperture in the crown plate with the flange of the T-section bearing against,

the under side of the crown plate. the lower end of said strut entering the casing slot.

6. A building column comprising :1 casing slotted adjacent its end, an apertured crown plate on the end of the casing, a

strut of T-section, a lug on its outer end engaging the aperture in the crown plate with the flange of the T-seetion bearing against the under side of the crown plate,

the lower end of said strut entering the casing slot, and a toe on the lower end of the strut bearing against the outer wall of the casing below the slot.

7. A building column comprising a casing slotted adjacent its end, an apertured crown plate on the end of the casing, a strut of T-section, a lug on its outer end engaging the aperture in the crown plate with the flange of the T-seetion bearing against the under side of the crown plate. the lower end of said strut entering the casing slot. the slot walls and web of the strut being welded together and the crown plate and strut being permanently united.

In testimony whereof I have atlixed my signature.
